る。C1 Conventional technology Currently, food and beverages such as coffee drinks are often sealed in food and beverage containers such as steel cans, aluminum cans, and bottles, and conventionally, retort devices ( Pressure-resistant containers for sterilization are known. In this retort device, the food/drink container is placed in a pressure-resistant container main body whose opening can be sealed, and steam at a predetermined saturated vapor pressure is introduced and filled into the pressure-resistant container main body, and heat treatment is performed for a predetermined time.

度に設定できるようにしである。When introducing this water vapor, the inside of the pressure-resistant container body is evacuated by 4 degrees in advance using an air vacuum device, or the air is gradually released while introducing the water vapor so that the inside is in a state of only water vapor, and the predetermined saturated water vapor pressure is This allows you to set the temperature to a predetermined value.
Ｄ２発明が解決しようとする課題
ところで、これらの飲食用容器のうち、例えばアルミ缶
はアルミ自体の強度が小さい上、缶の肉厚が極めて薄い
ので、そのままでは生産・処理の取り扱いに耐えられず
、凹んだり破損してしまう。D2 Problems to be solved by the invention By the way, among these food and drink containers, for example, aluminum cans have low strength and the wall thickness of the can is extremely thin, so they cannot withstand handling during production and processing as they are. , causing it to become dented or damaged.
これを防ぐために、アルミ缶内に窒素ガス等のガス体を
内容物とと乙に封入し、内圧を大きくしである。To prevent this, a gas such as nitrogen gas is sealed inside the aluminum can to increase the internal pressure.
その結果、水蒸気のみでレトルト装置内を所定の設定温

内圧が、１１η記飽和水蒸気圧による外圧より高くなり
、その差圧がアルミ缶の強度を越え、アルミ缶が破裂し
てしまうという問題点がある。As a result, if the inside of the retort device is brought to a predetermined set temperature using water vapor alone, only a predetermined saturated water vapor pressure can be obtained, so the nitrogen gas inside the food and drink container thermally expands and the internal pressure of the food and drink container increases to 11η. The problem is that the saturated water vapor pressure becomes higher than the external pressure, and the pressure difference exceeds the strength of the aluminum can, causing the aluminum can to burst.

Even if the internal pressure increases due to thermal expansion of the gas filled in the food/drink container by the retort device, the external pressure inside the retort device is increased to prevent the differential pressure between the external pressure and the internal pressure from exceeding the pressure resistance strength of the container and destroy the container. The purpose is to prevent

圧容器本体２に導入されるようになっている。The aluminum can 5 is filled with contents 6 such as coffee drinks and oolong tea as well as gas 7 such as nitrogen. Since the strength of the aluminum can 5 is weak, this gas 7 is used to increase the internal pressure to prevent it from being dented or destroyed during the manufacturing process. Furthermore, this gas also serves to prevent oxidation and deterioration of the contents. Then, the air 11 at a predetermined pressure is heated to the water vapor IO, which is set to a saturated water vapor pressure at a predetermined temperature by the air supply/control mechanism 9, and the air supply pipe! 2 into the pressure vessel main body 2.

等の飲食用容器５が殺菌処理されるのである。First, one lid 3 of the retort device 1 is moved and a plurality of aluminum cans 5 accommodated in the basket 8 are opened from the opening 2a.
It is carried into the pressure container main body 2 by a carrier, and the lid body 3 seals the opening 2a. Contents 6 are contained in the aluminum can 5.
In addition, the aluminum can is filled with nitrogen gas 7 to increase the internal pressure to increase the strength of the aluminum can. Then, the air inside the pressure vessel main body 2 is removed by the exhaust control system 4, and the air supply control system
steam IO at a predetermined temperature and saturated vapor pressure and air 11 at a predetermined pressure are introduced by the fan 13.
and air 11 are mixed uniformly. The aluminum can 5 is heated in the steam 10 at the saturated steam pressure for a predetermined period of time. At this time, the nitrogen gas 7 inside the aluminum can 5 thermally expands and its internal pressure exceeds the pressure resistance of the aluminum can 5, but the air mixed with water vapor l! The external pressure increases by the amount of pressure, and the pressure difference between the external pressure and the internal pressure does not exceed the pressure resistance of the aluminum can. As a result, rupture and deformation of the aluminum can 5 due to thermal expansion of the nitrogen gas 7 can be prevented. After being heat-treated in this way, the exhaust control system 14 gradually exhausts the air and controls the temperature to gradually lower.Then, the water supply control mechanism 15 and the drainage control device +MI6 cool the aluminum can 5 with hot and cold water. , the basket 8 containing the aluminum can 5 is carried out by the carrier from the opening 2b opened by the movement of the lid 4. This process is repeated one after another to sterilize the food and beverage containers 5, such as aluminum cans, filled with the contents 6 and gas 7 such as nitrogen gas.
なお、前記実施例において、飲食用容器としてアルミ缶

る。H. Effects of the Invention As is clear from the above description, the present invention provides a method for storing a container sealed with contents and gas in a pressure-resistant container main body whose opening can be sealed in a manner that allows the container to be inserted into and removed from the pressure-resistant container main body. In a retort device that heats the interior by filling it with high temperature steam,
In addition to introducing pond gas into the main body of the pressure-resistant container, a fan was installed to mix this gas with the steam, so the gas filled in the food-drinking container was thermally expanded by the retort device, increasing the internal pressure. This also has the effect of increasing the external pressure inside the retort device, preventing the differential pressure between the external pressure and the internal pressure from exceeding the pressure resistance of the container, and preventing the container from breaking.
